What is the precipitate resulting from the double replacement reaction BaCl2 AQ 2NaOH?
What is the precipitate resulting from the double-replacement reaction BaCl2(aq) + 2NaOH(aq)? A blue precipitate forms in the double-replacement reaction Ca(OH)2(aq) + Co(NO3)2(aq).
How can a chemical equation be balanced?
If each side of the equation has the same number of atoms of a given element, that element is balanced. If all elements are balanced, the equation is balanced.
Why is it important to balance a chemical equation?
A balanced equation obeys the Law of Conservation of Mass. This is an important guiding principal in science. Finally, a balanced equation lets up predict the amount of reactants needed and the amount of products formed.
How are balanced equations made more informative?
(a) The various ways in which a chemical equation can be made more informative are : (i) By indicating the physical states of the reactants and products. Example: Gaseous state is indicated by the symbol (g). (ii) By indicating the heat changes taking place in the reaction.
Why is digestion called a chemical change?
Food digestion is considered a chemical change because enzymes in the stomach and intestines break down large macromolecules into simpler molecules so that the body can more easily absorb the food.
What is combine reaction?
A combination reaction is a reaction in which two reactants combine to form one product.
What is the difference between a coefficient and a subscript?
Subscripts – Part of the chemical formulas of the reactants and products that indicate the number of atoms of the preceding element. Coefficient – A small whole number that appears in front of a formula in a balanced chemical equation
What does it mean when a number has a subscript?
A subscript or superscript is a character (such as a number or letter) that is set slightly below or above the normal line of type, respectively. It is usually smaller than the rest of the text. Subscripts appear at or below the baseline, while superscripts are above.
What does it mean when a symbol is not followed by a subscript?
A subscript shows the number of atoms of an element in a compound. The subscript always refers to the symbol just before it in the formula. If there is no subscript following a symbol, it means there is only one of that kind of atom in the molecule.
What are the steps of superscript?
Use keyboard shortcuts to apply superscript or subscript
- Select the text or number that you want.
- For superscript, press Ctrl, Shift, and the Plus sign (+) at the same time. For subscript, press Ctrl and the Equal sign (=) at the same time. (Do not press Shift.)
How do you use parentheses to balance an equation?
Remember with subscripts, any number to the right of parentheses multiplies each subscript within the parentheses. eg Fe2(SO4)3 contains 2 Fe atoms, 3 S atoms and 12 O atoms. 5. Finally make sure that all the coefficients are in the smallest possible whole number ratio.
Why do chemists use parentheses?
1 Expert Answer In chemistry, we use parentheses to help identify that there is more than one polyatomic ion present. There is only one sulfate ion so no parentheses is needed
